Samsung 65" U8000H Crystal UHD 4K TV vs Onn 65-Inch 4K Roku Smart TV

Both are 65-inch 4K LED TVs with HDR and 60Hz panels, so the picture hardware is close. The Samsung U8000H adds a stronger processor, better motion handling, Samsung Gaming Hub for cloud games, and Samsung TV Plus free channels. The Onn runs Roku, which most people find faster and simpler than Tizen, and owners consistently praise its picture and setup. Buy the Samsung for gaming and upscaling; buy the Onn for the smoothest smart-TV experience at the entry level.

  • Choose the Samsung U8000H if you game, watch a lot of lower-quality streams you want upscaled, or want free live channels without an antenna.
  • Choose the Onn 65-inch Roku TV if you want the simplest interface, quick setup, and a TV that owners rate highly for everyday streaming.

What reviewers say

Samsung 65" U8000H Crystal UHD 4K TV

Owner feedback on Samsung's entry 4K sets is mixed: people like the picture for the price and the free channels, but note weak black levels and average sound.

What people mention
  • Picture qualityMixedOwners call the 4K picture sharp and colorful but say dark scenes look gray.
  • SoundCriticisedReviewers say the built-in speakers are thin and a soundbar is worth adding.
  • SetupPraisedOwners find Tizen easy to set up and navigate.
  • Free channelsPraisedSamsung TV Plus is a commonly cited plus for free content.

Onn 65-Inch 4K Roku Smart TV

Owner feedback on Onn's 65-inch 4K Roku TV centers on value: people are happy to get a big 4K screen for very little money and like the Roku interface. Complaints tend to be about picture quality and sound, which are basic compared with name-brand sets.

What people mention
  • Picture qualityMixedOwners call the 4K picture fine for the price but note limited brightness and contrast.
  • ValuePraisedBuyers repeatedly say the size-to-price ratio is the main reason to get it.

  • Roku interfacePraisedThe Roku home screen and app selection are called easy to use.

Questions and answers

Which is better for gaming?
The Samsung. Motion Xcelerator smooths fast motion at up to 4K 60Hz, and Gaming Hub streams games without a console. The Onn is a plain 60Hz set with no gaming extras.
Which has the better smart interface?
The Onn. Roku is faster and simpler, and owners consistently praise it. Tizen on the Samsung offers more built-in free channels and apps but takes more getting used to.
Which upscales older content better?
The Samsung. Its Crystal Processor 4K upscales lower-quality sources to near-4K. The Onn relies on standard panel processing, so cable and DVD content looks softer.
Which is more reliable?
Hard to say. The Onn has a huge base of positive owner ratings but some reports of sets arriving damaged. The Samsung is a newer model with far less owner feedback.
Is the Samsung worth stepping up to?
Yes if you game, want free live channels, or watch a lot of non-4K content. If you mainly stream Netflix and want the easiest menus, the Onn covers it.
Do both support voice assistants?
Both list Google Assistant and Amazon Alexa support. The Onn's own remote is basic, so voice control usually runs through a separate speaker or device.
